Touch Scrolling with finger swipe

Hello

How do I go about finger swipe/camera scroll effect in Construct 2?

like there is shop, with many items and swiping finger up or down, moves camera up or down if there is room to go bellow/up on layout?

I made this and it works in browser with mouse

but with cocoonJS app preview I get no result, speed returns as 0 always ;/

and as well as previewing page on ipad, swipe touch speed returns 0 ;/

I needed to use SpeedAT not SpeedID and it worked

can you share the capx?
